Kim Kardashian finally gave the world a peek at her baby boy. The "Keeping Up with the Kardashians" star posted a pic of the 4-week-old baby, Saint West, on her website on Saturday, January 2.

Titled BFFS, the photo shows Saint's hand grasping his 2-year-old sister North West's finger. His face cannot be seen. "She said, 'He's my best friend'," Kim captioned the pic posted on KimKardashianWest.com.

Saint, Kim's second child with rapper Kanye West, was born on December 5. He weighed in at 8 pounds and 1 ounce. Before conceiving him, Kim said pregnancy was such a difficulty for her due to medical issues. "It's all worth it in the end, so I would definitely suffer through that, but pregnancy was not a good experience for me. At all," she told Ellen DeGeneres in January 2014.

"My labour was easy, but just the whole pregnancy was so... I had a few medical issues, so it was really tough, and I gained a lot of weight," Kim elaborated about her first pregnancy, adding "I think with all of the medical issues - I had Pre-eclampsia, which was really tough; I had to deliver early. But I wouldn't take any of it back because I have the most adorable, sweetest baby in the world."

Saint was visibly missing from the family's annual Christmas party and New Year's Eve celebration. Talking about her new year resolutions, Kim wrote on her website, "In the next coming months I'd obviously like to shed the baby weight. That's the big one to accomplish first!"
